The most plausible reason why your new patient, Elisa, is feeling tired all the time is:
Her body is unable to break down the starch into glucoseAccording to the complete question, we can see that the cells which are in Elise's body are receiving oxygen and proteins, but they are not getting enough glucose, which can be gotten from breaking down starch.
As a result of this, we can see that the best diagnoses of why Elise is always getting tired is that she has diabetes because of the inability of the body to break down starch to provide enough glucose to the body.

What is oxidation number?An oxidation number is a number assigned to atoms in molecules to show the general distribution of the electrons.
Oxidation state or number helps us describe the transfer of electrons.
The oxidation number/state is also used to determine the changes that occur in redox reactions.
Overall, the oxidation number of an atom in a molecule is the charge that the atom would have if all polar covalent and ionic bonds resulted in a complete transfer of electrons from the less electronegative atom to the more electronegative one.
Therefore, The oxidation numbers of the atoms in this reaction are 0 for Mg(s) and H in H₂, -1 for Cl in HCl, +1 for H in HCl and +2 for Mg in MgCl₂

The pink-nosed puppy and the black nosed puppy must not actually be related.
B.
The pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents.
C.
The pink-nosed puppy has a different number of chromosomes than the black nosed puppy.
D.
The pink nosed puppy and the black nosed puppy have different chromosomes for the two nose colors.
Answer:
I thin its B im not sure though
Explanation:
The puppies from the same set of parents have different color noses because the pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. Thus, the correct option is B.
What is a gene?A gene is the unit of inheritance which is made up of DNA (deoxyribonucleic acid). Every person receives two copies or alleles of each gene which is inherited from each of the two parent.
Genes are made up of DNA, so each of the chromosome contains many different genes. Genes carry the information which determines the traits or characteristics that are passed on to their offspring or inherited from the parents.
The puppies from the same set of parents have different colored noses because pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents.

In an aqueous solution, a 0.100 M solution of glucose is prepared with a total volume of 0.150 Liters. If the molar mass of glucose is 180.16 g/mol how many grams must the solution contain?
Answer:
2.70 g of glucose.
Explanation:
The following data were obtained from the question:
Molarity of the glucose solution = 0.1 M
Volume of solution = 0.15 L
Molar mass of glucose = 180.16 g/mol
Mass of glucose =.?
Next, we shall determine the number of mole of glucose in the solution. This can be obtained as follow:
Molarity of the glucose solution = 0.1 M
Volume of solution = 0.15 L
Mole glucose =?
Molarity = mole /Volume
0.1 = Mole of glucose /0.15
Cross multiply
Mole of glucose = 0.1 × 0.15
Mole of glucose = 0.015 mole
Finally, we shall determine the mass of glucose in the solution as follow:
Mole of glucose = 0.015 mole
Molar mass of glucose = 180.16 g/mol
Mass of glucose =.?
Mole = mass /molar mass
0.015 = mass of glucose /180.16
Cross multiply
Mass of glucose = 0.015 × 180.16
Mass of glucose = 2.70 g
Therefore, the solution contains 2.70 g of glucose.
The grams that the solution must contain is :
- 2.70 g of glucose.
Mole ConceptGiven:
Molarity of the glucose solution = 0.1 M
Volume of solution = 0.15 L
Molar mass of glucose = 180.16 g/mole
Molarity of the glucose solution = 0.1 M
Volume of solution = 0.15 L
Molarity = mole /Volume
0.1 = Mole of glucose /0.15
Mole of glucose = 0.1 × 0.15
Mole of glucose = 0.015 mole
Mole of glucose = 0.015 mole
Molar mass of glucose = 180.16 g/mol
Mass of glucose =.?
Mole = mass /molar mass
0.015 = mass of glucose /180.16
Mass of glucose = 0.015 × 180.16
Mass of glucose = 2.70 g

A gas expands from 285 mL to 789 mL at constant temperature. How much work is done by the gas (joules) if it expands against a constant pressure of 6.00 atm?
Answer:
-306j
Explanation:
For this question we define an equation:
W = -Pext(Vj-Vi)-----> eqn 1
P = 6atm
Vi = 285 ml
We convert it to litre
= 285/1000 mL
= 0.285 L
Vj = 789 mL
When converted to litre
= 789/1000 mL
= 0.789 L
These values are all going to be put values in the eqn 2 above
W = -Pext(Vj-Vi)
W = -6.0x (0.789L - 0.285L)
W = -3.024
W = -3.024 x 101.33 J
This gives us the answer
W = -306 J
Thank you!

A very new item just arrived in the market. It is very good for construction, and other things. Now, this item has chemicals, and in every drop, there are 400 grams of NaCI. If there are 10 drops in this item, how many grams of NaCI are in one bottle?
Answer: 4,000 grams of NaCI
Explanation:
We know that there are 400g of NaCI in one drop.
This bottle has 10 drops of this item.
So, we have to multiply the amount of NaCI in a drop by the amount of drops.
400 x 10 = 4,000.

A binding protein binds to a ligand L with a Kd of 400 nM. What is the concentration of ligand when Y is (a) 0.25, (b) 0.6, (c) 0.95?
Answers: (a) 133.33nm (b) 600nm (c) 7,600nm
Answers above are correct. Please show all steps, really trying to understand.
Answer:
(a) 133.33nm
(b) 600nm
(c) 7,600nm
Explanation:
The concentration of Y can be determined by using the formula:
[tex]Y = \dfrac{[L]}{k_d+[L]}[/tex]
where;
[L] = concentration of the binding ligand.
kd = 400 nm
Thus:
When Y = 0.25; we get :
[tex]0.25 = \dfrac{[L]}{400+[L]}[/tex]
0.25 (400 + [L]) = [L]
100 + 0.25[L] = [L]
100 = [L] - 0.25 [L]
100 = 0.75 [L]
[L] = 100/0.75
[L] = 133.33 nm
At, Y = 0.6
[tex]0.6 = \dfrac{[L]}{400+[L]}[/tex]
0.6 (400 + [L]) = [L]
240 + 0.6[L] = [L]
240 = [L] - 0.6 [L]
240 = 0.4 [L]
[L] = 240/0.4
[L] = 600 nm
At, Y = 0.95
[tex]0.95 = \dfrac{[L]}{400+[L]}[/tex]
0.95 (400 + [L]) = [L]
380 + 0.95[L] = [L]
380 = [L] - 0.95 [L]
380 = 0.05 [L]
[L] = 380/0.05
[L] = 7600 nm
How does the number of atoms or molecules in a system affect its thermal energy?
A. A system with fewer atoms and molecules has more thermal energy.
B. A system with more atoms and molecules has more thermal energy.
C. The number of atoms or molecules does not affect the thermal energy of a system.
D. Thermal energy increases as the atoms and molecules in a system move more.
Answer:
D. Thermal energy increases as the atoms and molecules in a system move more.
Explanation:
Thermal energy is a form of kinetic energy possessed by molecules of a system. The measure of this kinetic energy in an atom is called heat.
The average kinetic energy of a system is the temperature.
According to the kinetic theory, the more the particles move, the more their thermal energy. Thermal energy is often predicated on the velocity of the particles of the medium.Is steel wool and vinegar an exothermic reaction? Explain.

what are 4 ways a mineral can form
Answer:
The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which new minerals form at the expense of earlier ones owing to the effects of changing—usually increasing—temperature or pressure or both on some existing rock type, and (4) hydrothermal, in which minerals are chemically precipitated from hot solutions within Earth.
The mineral can be formed from volcanic gases, oxidation, crystallization from magma, sediment formation, or deposition from a saline fluid.
What is a mineral?A rock can be described as a collection of minerals. A rock that becomes so hot it melts and many minerals come out in liquids that are hot enough to melt rocks.
Magma can be defined as a melted rock inside Earth, a molten mixture of substances that can be hot to more than 1,000°C. When the magma cools slowly inside the earth, which provides mineral crystals time to grow large enough.
Granite is a rock that produces from slowly cooled magma, consisting of the minerals quartz, plagioclase feldspar which is shiny white, pink potassium feldspar, and black biotite.
When magma will erupt onto the surface of the Earth, it is known as lava. Lava cools more rapidly than magma when it is below the surface and mineral crystals do not have time to form. But the chemical composition remains the same as if the magma cooled slowly.
The mineral can be formed through hydrothermal processes, weathering, and metamorphic and igneous environments.
